摘　　要：The simple model for 4f-5d transitions of lanthanide ions in crystals was extended to deal with the case of the octahedral crystal field,where for the t_(2)component of 5d orbitals the spin-orbit interaction could not be neglected due to incomplete quenching of the 5d orbital angular momentum.The energy levels for the 4f^(N-1)5d configuration and the relative line strengths for the 4f^(N)\4f^(N-1)5d transition were calculated in detail.The result was applied to the interpretation of the low-temperature 4f-5d excitation spectrum of Cs_(2)NaYCl_(6)∶Tb^(3+).
